For information about how to install and launch a mod, see Manual/Using Mods. You can also see the Troubleshooting page. This page illustrates some mods not designed for OpenArena, but for Quake 3 Arena (or for some other derivative games). Some of the features added by OpenArena probably will not be present, but the mods will be worthy anyway. Some mods could also be designed for ioquake3 or other idTech 3 forks. Check a mod's page for more specific informations (features, how to install, compatibility issues). For OpenArena-specific mods, please see the "Mods" page.
